Yuav ua li cas puas LED Blue teeb Tua Peb Ob lub qhov muag? !

Yuav ua li cas LED xiav lub teeb tua peb lub qhov muag? !

Pom hais tias muaj yog ib tug ntau ntawm cov khw muag khoom noj yog trumpeted ib tug tsom-iav, tej khw hu ua lub tsom iav computer tawg-pov thawj tsom-iav, tej yog hais tias cov kob xiav tsom iav (ob peb lub sij hawm raws li tus hma tsom iav), thiab, anti-nkees tsom-iav thiab yog tus fifth tiam ... OK! Kuv mam li nco dheev muaj ib co xav paub txog qhov no anti-glare anti-tawg anti-qaug zog.

Lub ntuj yog xiav, dab tsi raug mob tsis xiav lub teeb muaj?

Kuv cov tub, taus, taus, taus ntsuj plig muaj peev xwm tsuas ntxias nws tus kheej tom qab kev txom nyem los ntawm cov ruthless tyranny ntawm cov thawj coj. Yog, lub ntuj yog xiav, lub xiav xiav muaj cov plaub hau raug mob.

Siv ib tug los ze zog saib tag nrho cov ntaub ntawv hais txog cov txoj kev txhawj xeeb ntawm xiav lub teeb, thiab tag nrho lawv taw tes rau ib tug high-tech: LED. Yog, koj nyeem hais tias txoj cai, lub LCD, cov teeb, lub tsheb taws, txawm lub LEDs siv nyob rau hauv lub teeb xais.

Peb siv ntau tshaj plaws, qhov no dawb LED. Kom nws ci dawb, cia lub LED nti emit xiav lub teeb, thiab ces tus phosphor hmoov emits teeb daj, thiab tus ob xim ntawm lub teeb muab mus rau hauv lub teeb dawb. Tshwj xeeb rau cov xim palette, Yog hais tias koj xav tau tus LED yuav dawb, ua rau kom tus nqi ntawm cov kob xiav lub teeb. Yog hais tias koj xav tau cov LED rau sov li, txiav tus nqi ntawm cov kob xiav lub teeb.

Kuv paub hais tias tsis txhob hais tias peb txhua tus to taub hais tias cov feem ntau xiav lub teeb peb muaj nyob rau hauv peb lub neej txhua hnub yog los ntawm ib tug ntau yam ntawm LCD cov ntxaij vab tshaus. Yuav ua li cas yog ib tug ua kua siv lead ua zaub, ib zaug marketed raws li ib tug synonym rau noj qab haus huv, tau los ua ib tug nyab xeeb niaj hnub no, xov tooj ntawm tes mus xyuas hauv computer kom cov ntsiav tshuaj rau televisions?

Nyob rau hauv lub neej tiag tiag, txawm peb nyob nraum dag nyob rau hauv lub txaj nrog peb xov tooj ntawm tes los yog zaum nyob rau ntawm peb lub rooj nyob rau hauv pem hauv ntej ntawm ib lub rooj, lub xiav lub teeb ntawm ib tug LED teeb tseem bombard peb pas nrig hlwb. Lub zaum ces sab ib tug tshwm sim hais tias tom qab lub rhodopsin decomposition, cov ntaub ntawv uas tau tsim tom qab nws tau decomposed absorbed 330-420 nanobands ntawm violet thiab xiav lub teeb. Tab sis lub uv teeb hauv qab no 400 nanometers pom tsis tau tus tib neeg lub qhov muag. Yog li ntawd yog vim li cas xiav lub teeb yuav ua retinal kev puas tsuaj.

Muaj, mus rau hauv lub qhov muag ntawm tus blu-ray yuav dhau ib lub teeb rau thim rov qab, yuav twb decomposition ntawm rhodopsin ncaj yuav txo tau mus rau hauv ib txwm muaj nuj nqi ntawm rhodopsin, es ua raws li cov qub rhodopsin synthesis txheej txheem. Raws li ib tug tshwm sim, lub zog ntawm cov pas nrig hlwb tau zoo heev kho kom zoo, thiab cov tib neeg qhov muag tus muaj peev xwm mus ntes tau photons tau zoo heev lawm.

Tab sis, yog qhov no nce qib zoo? Nyob rau hauv ntxiv thwmsim, peb pom ib tug tshiab phenomenon: kev puas ntsoog. Raws li cov tib neeg qhov muag tej lub photon capture muaj peev xwm ua, lub apoptotic txheej txheem ntawm lub photoreceptor hlwb yog tshuab txais thiab cov retinal puas yog tshwm sim los thaum lub teeb illumination ntawm cov tib neeg qhov muag nce mus txog 380kj / m2.

Yog li ntawd, xiav rau retinal kev puas tsuaj, yuav tsum tsuas summed li nyob rau hauv tus txheej txheem no: ntau heev xiav lub teeb rau hauv lub retina thiab retinal photoreceptor muaj peev xwm zoo tuaj, thaum lub retina capture photons tom qab mus txog ib qhov nqi ntawm retinal hlwb pib tuag, thiab retinal kev puas tsuaj.
